SLog3 Thumbnails Display in Extended Dynamic Range - Need Rec709 Conversion in Project PanelOpen for Voting

Hello Adobe Community,I'm experiencing a thumbnail display issue with SLog3 footage in Premiere Pro 25.3.0 that I hope someone can help resolve. Current BehaviorSource Monitor: When I load SLog3 clips in the source monitor, they display correctly with proper Rec709 conversion. The color processing is set to "gang to active sequence color management" and the footage looks properly tone-mapped with normal highlights and contrast.Project Panel Thumbnails: The same SLog3 clips display in extended dynamic range in the project thumbnail view, showing completely blown out highlights and appearing very flat/washed out. This makes it extremely difficult to browse and select clips. My SetupPremiere Pro Version: 25.3.0 (June 2025)Camera: Sony (SLog3/S-Gamut3.Cine footage)Sequence Settings: Rec709 color spaceProject Color Management: Standard workflow What I've TriedBased on previous forum discussions, I've attempted:Auto-Detect Settings: Enabled "Auto-detect Log Video Color Space" and "Auto Tone-mapping" in Project Settings > ColorDisplay Color Management: Verified Display Color Management is enabled in Lumetri preferencesInterpret Footage: Tried color space override to Rec709, but this affects the actual color pipeline, not just thumbnail displaySpecific Issue with Settings TabI do know about the Lumetri Settings tab, but I've discovered a key limitation: when no sequence is selected, all "working color space" options are greyed out. This means I can only select the media color space (S-Log3) for my clips but NOT the output color space (Rec709). This appears to be why everything is displayed as extended range in the project thumbnail view. Loading a clip in the source window while a timeline with Rec709 settings is active displays it correctly, but the project panel thumbnails remain in extended dynamic range. Core ProblemThe issue seems to be that project panel thumbnails are only using the media color space (S-Log3) without applying any output color space conversion (Rec709) since no sequence context is available for thumbnails. The source monitor works correctly because it can reference the active sequence's color management settings. Specific QuestionIs there a way to:Set a default output color space for project panel thumbnail display?Force thumbnails to use sequence color management settings even when browsing clips?Override the thumbnail display behavior to show SLog3 footage tone-mapped to Rec709? Why This MattersWhen working with large amounts of SLog3 footage, having properly displayed thumbnails is essential for:Quick clip identification and selectionVisual continuity checking across shotsEfficient media organization The current extended dynamic range thumbnail display makes it nearly impossible to see shot content or assess footage quality from the project panel.
