When you say failed, do you mean the driver doesn't add it? Then it must be some pixel clock limit. 40 Gbps is supposed to allow at least 1485 MHz, but it sounds like you're getting around 1440 MHz, which doesn't make sense for HDMI 2.1. You can still get 150 Hz under 1440 MHz if you try the different timing options.
