Has anyone managed to control the “SDR Preview” / SDR rendering sliders in Lightroom Classic with a hardware controller?

Hey everyone, I’m trying to integrate a hardware controller (MX Creative Console) into my Adobe Lightroom Classic workflow and I’ve hit a limitation I can’t quite explain.

In Adobe Lightroom Classic there is a feature in the Develop module called:

“Preview for SDR display” (HDR/SDR rendering preview)

When enabled, it exposes additional SDR-related adjustment controls for how the HDR image is tone-mapped into SDR output.

What works

  • Standard Develop controls (Exposure, Contrast, Highlights, etc.) can be mapped and controlled via the hardware controller
  • Keyboard/mouse automation works in general for Lightroom

The issue

I cannot find any way to:

  • map or access the SDR-specific controls via shortcuts or external controllers
  • bind those SDR rendering sliders to hardware inputs
  • control them outside of direct mouse interaction in the UI

They appear to be fully UI-accessible, but not exposed to any control surface / mapping layer I can find.

Question

Has anyone managed to access or control these SDR/HDR rendering parameters in Lightroom Classic via:

  • MIDI
  • control surfaces
  • Stream Deck / similar devices
  • scripting / automation tools

Or are these controls effectively UI-only with no external API exposure?

Context

I’m trying to build a fully hardware-driven editing workflow (less mouse, more tactile control), and everything in Lightroom maps fine except this SDR rendering section, which seems “isolated” from the rest of the Develop controls.
