Can a overrated pressure for a tap cause too much cold water?

OK, struggled to write that question....

It takes ages for warm water to come through my bathroom tap. At first I thought it was just because a long run for the hot water. But the shower comes through warm quickly. and its in the same room.

Now, the hot water pressure is 0.1bar. The cold water for the shower is fed from the water tank.

The tap has a rating of 0.5-5 bar I think (Merano Oval Basin Mixer Tap with Waste - I bought it, didn't know about water pressure at the time!) and the cold is mains fed to the tap.

Is it likely this is why the cold tap stays cold for so long - to get warm water sooner, and not waste as much cold water, I need a new tap?

Is this a mixer tap fed by flexi hoses?

Yeah, copper pipe goes to just under the basin, then flexi.

There was a recent post where someone changed the flexi tails to copper and noticed a dramatic improvement.
I'm considering doing the same.
My be worth reading see if you have the same issue.
