See, that is where the advantage stops mattering. If you put cheap glass on D810E or 5Dmk3 or whatever, it still won't look that impressive. Better start with good glass and buy a lower spec camera. And if you already have decent K-mount glass, then get a K-3II. Switching systems is costly and often its not rewarding. Besides, all current Pentax cameras have Sony sensors, anyway.
But in terms of image quality, there have been all sorts of tests done that were meant to show that people cannot tell apart FF and APSC, or even MF, or m43 sensors. Sure, some photographers know what to look for, and some photographers push their gear to the limit where even small differences matter. But for a huge chunk of photography, if you have good light and good glass, a regular audience would not notice or care to notice what sensor size was used
