ByteArrayFormatQ[ba,{"fmt₁","fmt₂",…}]

gives True if ba might be imported as one of "fmt_i".

Details

ByteArrayFormatQ attempts to identify whether a ByteArray object can be imported as a specific format.
ByteArrayFormatQ uses heuristic methods and may not give correct results, particularly for shorter arrays.
ByteArrayFormatQ does not verify that ImportByteArray would succeed if applied to ba.
