If use withIccProfile('p3') instead keepIccProfile() then the result is correct, what is the reason, is this a bug?

This relates to #3906 - I've added the P3 fix via commit 75fedf1 - thanks for reporting.

v0.33.3 now available with the fix, thanks again for reporting this.

I checked, yes it works correctly in the new version, thanks
