I did check on my system. The Compression Quality selection is not available for ProRes clips. What version of Resolve are you using? Even if the compression quality selection is available for some reason, I don't believe it will affect ProRes. If you want to prove that, just render a short clip twice, using the 2 compression quality extremes, and see if the file size changes. I don't believe it will.
For clips the compression quality selection works with, such as MPEG4 and H.264, the Best mode would give you the best quality, with less compression.
