It could be, but that's not necessarily the case. There's very little demand on the hydraulic system when you're just flying along, so very little fluid is actually being pumped through the system(s). So warm is probably the worst case.
Think of if as being a little like the hot water in your house. The water in the water heater may be hot, but until there's demand the hot water is basically limited to the the heater. What comes out of the faucet isn't hot initially - you have to wait for the hot water to flow from the tank to the faucet.
That's not to say that the hydraulic fluid in the tank is kept hot. The heat is generated as a by-product of the pumps producing pressure plus just absorbed heat from the engines.
