[Star Wars] Was it difficult for the Rebellion to get Luke a prosthetic that looked that lifelike?

There are a lot of Imperial officers from the original trilogy era whose prosthetics are much more visibly mechanical despite the fact that they belong to the better funded side of the Galactic Civil War. Was it hard to get Luke a prosthetic that was so similar to a real hand, or is that just the industry standard for civillian-grade prosthetics?

Unlike the Empire the Rebellion couldn't afford to lose their officers and high ranking members, it makes sense that they'd provide them with superior prosthetics to maximize their chance of survival and ensure that their combat effectiveness wouldn't be compromised. Any kind of prosthetic is also a dead giveaway that someone is a War Veteran or is atleast involved in dangerous work, so it makes sense to provide Rebel Officers with life-like prosthetics to disguise them when they're operating in Imperial territory.

In comparison, the Empire had a massive manpower pool which ensured any lost officers would be quickly replaced; the Empire also evidently cared little for their officers since Darth Vader would regularly cut through them himself without any consequences. With this is mind, there's no reason to believe that they would be provided with high quality prosthetics. Just like the Star Destroyers and Tie Fighters, which weren't particularly brilliant in their given role but were 'good enough,' mechanical prosthetics fulfilled their function to an acceptable standard and anything better was deemed an unnecessary expense.

It's also important to mention that superior funding does not translate into better equipment. You'll get better trained and equipped soldiers using 500,000 credits to arm and train 500 men than by using 5,000,000 credits to arm and train 1,000,000 men. Obviously the latter army has vastly superior numbers, but that doesn't really matter when your entire military strategy is based around hit and run tactics.
