I know the yellow/gold you mean , everybody likes it , many public buildings are illuminated with this colour .... Unfortunately RGB strips do not produce it at all well ... in theory they should produce any shade of any colour , but to get a good yellow/gold , you have to buy yellow strip ...mostly will run in yellow color but why not to have all colors and include.
Its was a hard decision for me to choose Yellow leds or RGB. I go with RGB because i can play with colors sometimes.I know the yellow/gold you mean , everybody likes it , many public buildings are illuminated with this colour ....

As for your question ,very rarely will you have all 3 colours full power , often just one full and another half etc ... this probably won't overload the controller ... if nervous put a resistor on the common line this will limit current slightly and you will never notice difference in light output and the strip will have a much longer life if not run at max.
Good point. Here are details of Gate Threshold VoltageBefore just swapping in a random FET, check what voltage level is being applied to the gates of the existing FETs.
Review the datasheet of the replacement part to determine if the gate voltage is sufficient to turn them on fully.
White is not when all 3 colors are at 100%.
Your multimeter cannot measure the PWM dimmed voltage.
