absolutely.
there are many great clean rigs in the Rig Exchange (even some Polytones), there JC-120 rigs in the factory content, as well as super clean Deluxe, AC30, Bad Cat profiles.
also, turning down the gain to zero on crunch profiles works really, really well.
and since you can sort all profiles by gain, they're easy to find.
the upcoming Vintage Sound Project Rig Pack will also adress cleans (as well as crunch sounds)
I use for clean jazz guitar tones, both with a solidbody guitar and with a hollowbody. It's great with both!
Here's a short clip I did with the solidbody, a PRS DGT. This tone is brighter than the typical jazz guitar but the KPA does that just as well.

and yes the KPA has absolutely gorgeous clean tones !
I also play with a solidbody or archtop, and you can find profiles of famous Fender clean amps for instance which are perfect for jazz !
Yes ! I had to take a little time to adjust clean rigs of vintage and modern vintage amps : Dr Z 28 (Rig ex) and D'lux cactus (Factory rigs) , most rigs sound boomy without tweaking on my monitors.
Here is a demo with an archtop (clean ) on the right (Left is a strat on rotovibe)
It's better if you tweak your own rigs but if you are in trouble I'll send you mines. Adjust EQ , try with different cabs and also adjust Freq shifting for lows and highs in the CAB menu.
Enjoy !

no offence, but boominess often is caused by having the monitors stand directly on a hard surface (no isolation pads), by the placement of (rear ported) speakers too close to a wall or much worse, a corner, or by the room itself (standing waves, no bass traps)

Not sure about this , other guitars never get boomy and this Washburn sounds also boomy on my real JTM30 tube amp , I suspect the setup of my pickups or the PU themselves as well as the huge body of the JS6. However this is easily adjusted with swapping cabs & Freq Sh. On the other side those Jazzbox rigs sound very thin on other guitars.
Some jazz players report to be happy with the Ampeg profile
I've found music videos and clips of many genres posted in the wikpa.org

Some jazzy white christmas

Wow, these are great! I love the Mr Sandman clip.
I am a real bad jazz player BUT, with my PRS HB, I have found a lot of profiles to get great Jazz sounds : Studio clean Package from Amp Factory, some Fender profiles and
some "dumble-like" profiles.
I'm confident you will find some real interesting profiles for Jazz !

It is great for jazz. I like many profiles and as others have suggested Fender amps always were one of my favorites for jazz. I just bought a single profile of a Vintage Blackface Twin and it is my latest favorite with my Benedetto Benny guitar. I would love to get a pair of really small FRFR speakers for use with it, like something with 10 inch or maybe even 8 inch speakers for portability for jazz gigs. In stereo it sounds great if you like a more modern sound with some delay, verb and/or chorus.
I've been looking up the Youtube vids for Kemper and found many people demoing the hi gain sounds,
On a side note, I believe that metal guys are everywhere nowadays! Any and each new piece of software, app, simulator, modeller... coming out (have to) show their ability or facilities in the heavy tones territory. Usually, the first packs released by any of the before-mentioned tools are related to Metal. These guys do have a great market share for sure.
I must admit, I can expose myself to certain kinds of very heavy music for no longer than a few seconds per time, but I've realized that it's a very, very technical approach, specially as regards seeking tones. Heavy guys are really nerd, so to speak! No surprise that they are on the front line when a new technological device jumps up. But basing any statistic on this would be misleading IMO 
We're in the process of recording the Christmas Seeds album that will be released next year. I'm using a 1961Gibson ES175 through the Kemper with the Fender VibroChamp profile for the clean preset; it sounds amazing!! I haven't yet settled on my distortion profile but have been leaning on the 1970 Marshall 100 watt, with guitar set on 8 and amp set to 11 o'clock on the volume.. it's got a nice southern rock smoothness like Dickey Betts... it needs the open back Marshall cabinet mod to get it just right but I'm pretty happy so far... I'll post something up as we get our tracks in and a rough mix.. I love the Kemper sound and am happy with the effects... mega cool for jazziness.
Did a test profile of a Jim Kelley amp through a Two Notes Torpedo Live using the Voice 65 cab and with the gain and presence turned down a bit it's incredible with a jazz box.
