DeNoise AI vs AI Clear

Interesting topic. I am here because I shoot architecture and sometimes I need to get rid of noise from my drone shots. I used AI Clear in Studio 2. Generally I like it as it produces crisper images, however, I have noticed a color shift on some images. Where to solve this I had to mask out the building so no change of color. I did a google search on this and others have found the same with AI Clear Studio 2 but not with DeNoise. Any idea what is going on?
