HDRDisplayCalibrate 0.3.0 (preview)

Tested end to end on a real monitor. A full SDR and HDR calibration of an ASUS VG34VQL3A with a ColorMunki Display gave:

• SDR: white ΔE 1.15, greys ΔE avg 0.97 / max 1.56, gamma 2.18
• HDR: white x 0.3124 y 0.3304 (D65), PQ tracking 93–97 % of target from 5 nits up, peak 270 cd/m²

Screenshots are in the README and in docs/run.

Fixed (found by that run)

• HDR (MHC2) profiles had a misplaced header field, so Windows ignored them.
• SDR profiles were saved without their calibration curves (vcgt).
• After installing a profile, Windows could reload the old curves; the app now loads the new ones again.
• Long measurements no longer let the display go to sleep, and the app wakes a display that already did. If the sensor sees no light, the app says so.
• If the target white luminance is out of reach, the app now says so before dispcal starts, instead of dispcal chasing it for hours.

New

• What to do guides on the SDR and HDR pages.
• A profile prompt with Show the profile file, Copy path and Open display settings. Windows applies a profile only after Set profile is pressed in Settings → Color management.
• SDR profiles are also associated per device, the classic way calibrite PROFILER uses.
• An optional sign-in loader that loads every display's calibration at sign-in, plus a warning when Windows' own Calibration Loader is switched off.
• All new texts are translated into all 11 languages.
