So - regarding the black crush problem on inFAMOUS that myself and some other people are having, I got an email response back from Sucker Punch regarding the issue:
"Dear
Thank you! We at Sucker Punch are constantly striving to improve our quality and integration with the gaming community, and your report will help us do that.
We would like to inform that we investigated the brightness issue that surfaced after the PS4 Pro patch, we successfully determined the cause, and we are currently working on a new patch that will expose the legacy brightness/contrast behavior, as a user choice. Our goal is that, by doing this, we will be able to accommodate the different brightness behaviors we are observing, depending on the brand and model of the TV being used.
We are finalizing the new code, and should have this new patch ready soon.
Thank you for your support!
Sucker Punch Team"
So basically another patch is coming that should fix things for those affected. Really pleased at the quick response, I loved my First Light playthrough even with the black crush (I played with my TV settings to improve the issue, but it didn't completely fix it) so a complete fix would probably prompt me to replay it (and Second Son) again as the improved frame rate is such a big improvement for the game for me.
