There’s no inherent difference between those modes afaik, you can set any parameter freely. Of course, the real difference is the line count + refresh rate of the signal, so if it doesn’t work it’s because your display isn’t compatible with the particular pixel clock achieved with the required sample rate (in combination with what it deems acceptable active area/total area). That’s the difference compared to the generic mode, where you can set the samplerate freely until you find a pixel clock range that your display accepts (and gives acceptable aspect ratio). In optimized mode the pixel clocks will be fixed to the integer steps of the optimized samplerate, so it’s less flexible.
