Questions about MSI MAG 271QP QD-OLED X24

Are the labelling for all the monitors on Galaxus wrong when it comes to Energy Consumption ? For example : This is listed as "A" but when i click on it it's actually "G" If i want to look at the most energy efficient monitors and I set that in the search filter, the lablelling always seems inaccurate. I might be the one reading it wrong, please clarify this to me, thank you very much.

Hello, will you also offer the 500 Hz and is there any information on availability? (MPG 271QR QD-OLED X50 & MAG 272QP QD-OLED X50)
