The grease in the sealed bearing will still see the same pressure changes I think.

I have been spin-testing my bearing with the supplemental seal and it spits out a little grease each time I start spinning it after a cool down period. I have a feeling my prediction may be correct. It may be that using grease will require some type of ventilation.
