Yes, but at least a real hologram creates an actual depth sensation as the eye's focus needs to adapt. This means 3d impression works even for people with reduced stereoscopic eyesight, and does not create headaches due to a mismatch of scene depth vs. physical display depth. Such holographic displays do exist, e.g. www.seereal.com (which BTW recently received an investment by Volkswagen).
