T16 G1 - any chance to find out, if a display is the Low Power / 100% sRGB-type?

[Hummel]

Want to buy a T16 G1 (AMD) refurbished from a reseller. The displays are said to be 1920 x 1200 WUXGA. Is there any way to find out, if the display ist the "Low Power / 100% sRGB"-type without special equipment? The reseller told me he can't tell the exact type of display.

EDIT: Found some possible solutions here: https://www.reddit.com/r/thinkpad/comments/hazsjx/how_to_check_if_the_display_panel_is_lowpower/

Using https://support.lenovo.com/de/de/parts-lookup to search for the serial-number seems to be the best option.
