In general, a provider code corresponds to a company/organization, and the name should be that of the company, not of a given feature. The feature is signalled in the "provider oriented code". The exception is HDR Vivid, where the code 0x0004 indicates the HDR Vivid feature itself rather than CUVA (China UHD Video Industry Alliance), according to the UHD World Associations 'HDR Video Technology Part 2-1 Application Guide to System Integration' document.
