デス・クリムゾンはメーカーロゴ[画面]{がめん}[以外]{いがい}[自称]{じしょう}ほど[迫力]{はくりょく}がない。
Other than its maker logo screen, Death Crimson is not as menacing as its namesake.
As with the sentence above, I can use 自称 for referring to namesake.
In another question, the phrase as it's claimed to be is suggested to be translated to 言われているほど. Can I use 自称 here instead? Like
我が国の教育制度は自称のほど良くない
To begin with, I do not think that the use of 自称 in the first sentence is correct. 自称 means how someone refers to him/herself (regardless of how others refer to him/her). For example, 自称音楽家 means a self-styled musician. (This example was taken form New Century Japanese-English Dictionary.) It is not really about a name, but about a self-claimed occupation or some other attribute of a person. I would say something like 名前から期待するほど instead of 自称ほど in the first sentence.
The use of 自称 in the second example is incorrect because 我が国の教育制度 (the education system in our country) does not refer to itself as something good.
