It seems that recent changes have broken several tests in calib3d and photo modules (https://github.com/opencv/ci-gha-workflow/actions/runs/13731764537):

calib3d:

  [  FAILED  ] 3 tests, listed below:
  [  FAILED  ] CV_RecoverPoseTest.regression_15341
  [  FAILED  ] Calib3d_SolvePnPRansac.double_support
  [  FAILED  ] Calib3d_SolvePnP.accuracy_planar_tag

photo:

  [  FAILED  ] 2 tests, listed below:
  [  FAILED  ] Photo_Decolor.regression
  [  FAILED  ] Photo_NPR_DetailEnhance.regression

These tests run on CanMV board and OpenCV has been built using Clang 17.

Probably one or several of the following PRs caused these issues: merged:2025-03-02..2025-03-08 I suspect it could be solve and or cvtColor, but I didn't check exact functions yet.

@amane-ame , @GenshinImpactStarts , @hanliutong , could you please take a look?
