Actually, the rules are the same. It is simply the difference on how they are enforced. FWIW - per my observation, as soon as your information is entered into the MPS system by any PSB, you should be able to use the eChannel regardless of the POEs in question.
But the problem is visa is at the national level and is not issued by MPS, but MFA instead, which is similar to the U.S. (State Department issues visa, but CBP controls the immigration). Of course - no PSB will take care of that for you.
Also - don't forget one of the major issue - Chinese is the official language. So when you communicate in English, PSBs have all the excuses not to understand (it is also one of the reasons why rules against foreigners are lax than Chinese).
