    will compressed texture be uncompressed into memory if the compressed format can't be supported by the hardware?

    Well, that is what I would expect and it is mentioned here:
    "Although Unity Android does support DXT/PVRTC/ATC textures, Unity will decompress the textures into RGB(A) format at runtime if those compression methods are not supported by the particular device in use."

    Though that's specific for Android, I expect it to be the general rule.

    I'm pretty sure that Android is the only platform where there isn't a standard for texture compression, so you shouldn't have this problem anywhere else.

    Having a compressed texture in memory in a format the hardware can't decode makes it unreadable. So my guess is yes, it will be either uncompressed, or compressed in another, supported format.
