Banding can be reduced via calibration. Prior to calibrating, when I put up the gradient test patterns, there were a few areas of gray that weren't uniform, disrupting the gradient. After a 20pt white balance, the same test pattern is almost perfect. You have to do this for SDR, HDR10, and Dolby Vision of course, to get it right in all three, and calibration isn't simple or cheap whether it's DIY or with an ISF pro.
The other factor is the source material, especially streaming or Cable/Sat programming. They use heavy compression that results in banding, posterization, and pixellation that are part of the encoding. That's not the TV. Even Blu-rays and UHD Blu-rays can have this problem, so it's not always the TV.
As far as slides go, personally I just watch normal stuff and break in the TV that way.
