Leica Q3/Q3M/Q343 Firmware 4.1: DNG Color Fix Is the Real Win

The DNG color matrix fix is the one to act on. If you shoot Q3 files through Capture One or DxO and your color presets have felt slightly off, that wasn't you. Leica quietly updated the matrices baked into the DNG, which means third-party software using those matrices for colour rendering now has accurate data to work from. Install this before your next edit, not after. The profile-switching freeze fix is also worth having if you run multiple FOTOS-toggled profiles on a single body. The focus peaking control change is sensible housekeeping: keeping peaking off in AF mode reduces visual clutter during fast work. Nothing here reshapes the Q3 as a platform, but the DNG fix alone justifies the update.
