The slight hamon is a possibility because 1095 is a shallow hardening steel and in thin cross sections, such as a knife blade, it will only harden to a certain thickness. This also depends on the grain size with smaller grain decreasing hardenability. As a result the blade will only harden up to that point, usually about an 1/8" with a good fine grain. Thicker than that pearletic steel is formed. You could try to bring it out more with ferric chloride or even lemon juice. Don't know about the orange peel effect. Normally I would suspect overheating but you use a high temp oven for austenizing.
