I feel Dolby True-HD is more of a "Pro" or "Premium" whereas DTS-MA is just run of the mill, nothing special anymore.
Neither Dolby nor DTS charges any licensing fees to use their codecs. While the studio must pay for the encoding software to author the discs with, this is a very small one-time expense that likely anyone on this forum could easily afford if we wanted.
I've spoken to both Dolby and DTS about this, and both companies have given me consistent answers. The reason home video studios choose one audio format over another has nothing to do with price, quality (both are lossless) or backwards compatibility (both formats are backwards compatible in their own ways). The choice comes down to which software is easier to use and performs the encoding faster.
Until the past couple of years, DTS software was more user-friendly for the studios and encoded a lot faster. (Even Dolby has admitted this.) As a result, most of the major studios switched to DTS-HD Master Audio as their audio codec of choice. Dolby eventually improved their software to be at least comparable to DTS, but by that point the studios had grown comfortable with DTS and saw little reason to switch back.
Recently, Dolby has added new features to its software that DTS doesn't have, such as 96k upsampling, in an attempt to regain ground on Blu-ray. Thus far, that hasn't proved as compelling a sales point as they'd hoped.
