The only thing I an assume is that when you chose ProPhotoRGB and thusly automatically setting everything to native gamma and color temperature with luminance not specified, that your native color temperature must take on a much bluer and brighter appearance.
Not sure, just have to ask when you choose this profile as a target does your screen immediately change in color cast? Mine does because its native color temp is quite off due to my display being 7 years old. Yours, I'm assuming being newer, is probably not as greenish yellow and either slightly cooler/warmer or more neutral.
A positive aspect for myself in this discussion is I just figured out how to get a null (straight black diagonal line) RGB curve to show up in my i1Match calibration assessment graph by choosing a canned ICC profile such as the ProPhotoRGB. I could never get i1Match to produce this using any other setting and I've been trying for years.
David, why did you ask if I was from Florida? Have you met any other Lookingbill's there. I have a son named David who once lived there. But to answer your question, no, I've never been to Florida.
